LOUIS STOCKSTROM, OF ST. LOUTS, MISROURT.

GASOLINE-STOVE.

Applicaticn filed (lune 10, 1885.

To all whom it may concern.

Be itknown that I, Louis STOOKSIROM, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in GasolineStoves, of which the following is a full, clear, and exact description, reference bci ng had to the accompanying d rawings, forming part of this specification, and in which- Figure 1. is a side elevation of my improved stove. Fig. 2 isa vertical section through the pump and valves. Fig. I; is a section of the pump-piston. Fig. t is a section of the valve closing the filling-opening. Fig. 5 is an elevation of the same open. Fig. (i is a top view of the valve-operating lever used with the pump. Fig. 7 is a modification showing a bellows that may be used instead of the pump. Fig. 8 is a top view of the same. Fig. 9 is a modification illustrating how my invention may be used with an ordinary blow-pipe, which cannot be used without opening the valve. Figs. 10 and 11 are modifications show ing how the valve J may be opened automatically when the lever of the. bellows is raised. Figs. 1, 7, S, 10, and 11 are views on aboutthe same scale. Figs. 2, 6, and t) are views on a larger scale. Figs. 3, -t, and .3 are views on a still larger scale.

My invention relates to that class of gasoline-stoves having an oil-reservoir located heneath the burner, and a pump for forcing air into the reservoir to cause the flow of oil to the burners.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the body of the stove having a table A, and B the burners, both of which. may be of any ordinary construction.

0 represents a reservoir for holding oil, lo cated near the bottom of the stove, or at least beneath the burners.

D represents the cylinder of a pump for foreing air into the reservoir to cause the flow of oil to the burners.

D is the piston of the pump, and D a hollow pistoirrod, on the upper end of which is a handle, 1).

The piston is preferably composed of adisk, D, having an internally screw-tln-eaded pro- ICAIION forming part of Letters Patent No. 350,087, dated September 28, 1886.

Serial No. 169,269. (No nmdel.)

jection, W, on top to receive the rod and an externally screwtbreaded projection, D", at bottom to receive a disk, D and a cap, 1). Between the disks l)" and l) is held a cup-leath er, I)", that forms a tight fit between the piston and cylinder. The disk D has an O'1)8l1 ing, D", with aseat, l), against which a valve 1), is held by a spring, 1), between it and the cap I), which has an opening, D, to receive the stem of the valve and to permit the pas of air when the valve is opened by the upward movement of the )ist0n, the air being supplied preferably through the hollow rod entering through a hole, D. When the pis ton israised, the valve opens downward, auto matically compressing the spring, and as soon as the upward movement ofthe piston ceases the spring closesthe valve, sothattheair which has entered the cylinder is forced by t he downward movement ofthe piston through a pipe, 1, into the oilreservoir 0, where it is held by valves J and L. The valve .T is loeat ed in a casting, J, between the pump and the pipe I, into which it screws. (See Fig. 2.) it extends up abovethe table of the stove, and on its upper end is a lever, .T", thatpvhen the valveis elosed,crosses the handle 1)" of the pump (see Fig. 6) to prevent the pump being worked without first turning the lever from over the handle and thereby opening the "alve. (See Fig. 2.) Then the pump has beenworked, the lever may be turned automatically over the handle by a spring, J, on thestem of the valve. Thetableof thestove is preferably provided with a cup, A, to receive the handle when in its lowest position. The valve L is located in a barrel, L, inserted in the pipe I, and it preferably consists of a fiat hollow piece of rubber or other suitable material, with a slit, L, to permit the passage of air through it when the pump is worked. \Vhile the air is passing through the valve is expanded into a tube; but as soon as the pump is stopped the valve collapses and prevents the return of the air, thus affording additional security to the valve J against the escape of air from the reservoir.

In Fig. 7 is shown a bellows for compressing the ail-instead of the pump, and the valve J is a barrel-valve with a handle, J, that has to be turned from across the lever that operates the bellows before the bellows can be worked. (See Fig. 8.) XVith this arrangement the valve J may be opened automatically when the lever is raised by reversing the action of the spring J and having it act to open the valve instead of close it. The valve is held closed by a projection, J on the stem of the bellows, against which the handle J bears, and as soon as the bellows-lever is raised the spring turns the handle and valve, opening the latter, which remains open while the bellows is being worked, as the lever is not lowered far enough to bring the projection J against the handle of the valve, and when the bellows is stopped the projection moves the handle around, closing the valve.

N represents the oil-pipes leading from the reservoir to the burners. The reservoir is preferably filled through a short pipe, 0, entering it a short distance below the top, so that it (the reservoir) cannot be entirely filled with oil, leaving a space above the oil for the com pressed air. The pipeis closed by a valve, 1?, secured to a stem, P, by a pin, 1?, fitting in a circumferential groove, 1?, in the stem, thus permitting the stem to turn without turning the valve and without wearing out its packing l on the seat. The stem screws through a yoke, P hinged to the pipe at P, so that the valve when opened to fill the reservoir can be turned over out of the way, as shownin Fig. 5, and when it is turned back it is stopped in a vertical position by lugs I thereon coming against lugsl on the outside of the valve-seat.

Instead ofa pipe being used to connect the V pump to the reservoir, an ainpassage of any kind could be casting.

I claim as my inventionused-a's, for instance, in a 1. The combination, with a gasoline-stove having an oil-reservoir, of an air-eompressor communicating with the reservoir, and avalve 7 located between theoompressor and reservoir having alever or arm which in its normal position stands in thepath of the compressor, rendering the compressor inoperative until the valve is opened, substantially as set forth.

2. The combination, with the reservoir ofa gasolinestove, of a compressor for forcing air into said reservoir, connection between the compressor and reservoir, a valve located in said connection, and which in its closed position prevents the pump from being operated, and mechanism for closing 'said valve automatically when the compressorhas been operated. v

3. The combination, with the oil-reservoir of a gasoline-stove, of an air-compressing device having a pipe leading'to the reservoir and a valve located in the pipe having a lever or arm extending in normal position over the compressing device, preventing access to the latter until the valve is opened by shifting the lever or arm, substantially as set forth.

l. The combination, with an oil-reservoir of a gasoline-stove, of an air-pump having a pipe leading to the reservoir, a valve located between the pump and reservoir havinga rod, J, closing-spring, and an arm or lever extending in normal position over the pump, rendering the latter inoperative until the arm-or 1ever is shifted to open the valve, substantially as set fortln LOUIS STOCKSTROM.
